Original BMW M3 E30 Meets the All-New M4 Coupe, Plus Preliminary Specs

| |

As it turns out, the first official photos of the 2014 generation BMW M3 sedan and M4 Coupe aren't the only things leaked about the high-performance cars.

A search on YouTube revealed that German magazine Autobild has also shared a video with footage of the M4 and its original predecessor, the M3 E30 (1985-1992), while also releasing final specs on the new model.

You can see the footage below, but in regards to the M4's new twin-turbocharged 3.0-liter straight six, it is said to be rated at 425hp (431PS) and 550Nm (406 lb-ft), with 400Nm (295 lb-ft) readily available from 3,900 rpm.

There are two 0-100km/h (62mph) times listed on the German publication's site and video, at 4.1 and 4.3 seconds, which we assume are for the optional seven-speed M Double Clutch Transmission and the standard six-speed manual gearbox respectively (we'll be sure when BMW comes out with the official release).
